What do grid lines represent in land navigation?

In land navigation, grid lines are essential for accurately determining a location on a map. They generally consist of a series of straight lines that create a grid pattern, effectively forming squares on the map. This grid system allows for precise measurements and helps navigators easily read coordinates, facilitating both route planning and the identification of features on the terrain. The organization of these lines simplifies the process of pinpointing locations, making it easier to communicate positions or navigate from one point to another.

Understanding the structure of grid lines is crucial for effective navigation and ensures that users can efficiently interpret and utilize maps in various terrain types.
